Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting nut intended to be used when an electric appliance or the like is fixed to a groove portion of a mounting rail.
[0002]
[Prior art]
Conventionally, as this type of mounting nut, a structure (utility model registration No. 2600212) is known in which a screw plate having a hooking protrusion and an elastic frame for holding the screw plate are combined.
[0003]
[Problems to be solved by the invention]
In the conventional mounting nut, when an electric appliance or the like is fixed to the mounting rail by a bolt tightening force, the mounting nut itself is also fixed to the mounting rail. For this reason, in a state where no electrical appliances are attached, that is, in a state where the mounting nut is inserted into the groove of the mounting rail and is not tightened with bolts, the mounting nut is inclined when the mounting rail is inclined. Slid along the mounting rail, and there was a problem that the predetermined position could not be maintained.
[0004]
In addition, many of the conventional mounting nuts have a structure that must be inserted from the end of the mounting rail, and must move an electric appliance or the like to a position to be fixed, to any position on the mounting rail. There was a problem that it could not be hooked directly.
[0005]
[Means for Solving the Problems]
The present invention solves the above problem by attaching a spring that can press a part of the screw plate to the lower surface of the groove edge of the mounting rail.
[0006]
That is, according to the present invention, a mounting nut used when mounting an electric appliance or the like on a mounting rail has a screw hole and a narrow grooved hook that can be slidably latched on the lower surface of the groove edge of the mounting rail. One end of a leaf spring bent in an isolated manner so that the screw plate can be pressed against the mounting rail is fixed to the lower portion of the screw plate, and the other end is slidably fixed to the mounting rail. At the other end of the spring, a rising portion whose tip abuts against the lower portion of the screw plate was provided, a rail abutting portion was provided, and a protrusion capable of making point contact with the base surface of the mounting rail was provided at the rail abutting portion. A mounting nut that is used when mounting an electric appliance or the like on a mounting rail, and has a threaded hole and a narrow grooved hook that can be slidably latched on the groove of the mounting rail. On the bottom of the screw plate Secure the small diameter end of the over-shaped coil springs, attached to pan the large diameter side of the coil spring, a mounting nut which is characterized in that a projection of the rail and abuts against the lower surface of the receiving dish.
[0007]
The screw plate is a mounting nut provided with a flange portion that can be inserted obliquely into the lower portion of the groove edge of the mounting rail and that can be slidably hooked to the groove edge.
[0008]
The spring can be formed by bending a leaf spring or a coil spring, but the essential point is that it exerts an appropriate pressing force and is easy to slide.
[0009]
As the spring material, a conventionally known material such as a metal or a synthetic resin can be used as long as it exerts an appropriate pressing force and is easily slidable.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a mounting nut used when mounting an electrical appliance or the like on a mounting rail, and has a screw hole at a lower portion of a screw plate that has a screw hole and can be slidably latched in a groove of the mounting rail. A mounting nut in which a spring that can be pressed against the mounting rail is slidably fixed to the mounting rail. The spring is a mounting nut in point contact with the mounting rail base surface.
[0011]
The screw hole is for screwing a bolt for fixing an electric appliance or the like.
[0012]
The screw plate can be slidably latched in the groove of the mounting rail, and a spring for pressing the screw plate against the mounting rail is attached to the lower portion of the screw plate. For this reason, the mounting nut hooked to the mounting rail is held between the groove edge of the mounting rail and the mounting rail base surface, and even when the mounting rail is inclined. There is no movement from the position once latched, and no slipping occurs.
[0013]
The mounting nut can be pushed and latched into the groove of the mounting rail by compressing the spring while inclining the flange of the mounting nut and pushing it into the lower surface.
[0014]
Further, when it is desired to move the mounting nut from the position once hooked, the spring is compressed and moved to a desired position by pressing the mounting nut toward the mounting rail base surface.
[0015]
Here, by bringing the spring into point contact with the mounting rail base surface, the friction between the spring and the mounting rail base surface can be reduced, and the spring can be moved smoothly.
[0016]
In addition, by providing the screw plate with a flange portion that can be slidably engaged with the groove edge of the attachment rail, the attachment nut can be stably attached to the attachment rail. Even when the mounting nut is moved, the mounting rail groove can serve as a guide for easy movement.
[0017]
[Example 1]
An embodiment of the present invention will be described with reference to FIGS.
[0018]
The mounting nut 1 has a screw hole 2 and a spring 5 that can press the screw plate 3 against the mounting rail 4 at a lower portion of the screw plate 3 that can be slidably engaged with the groove 4 b of the mounting rail 4. It is configured to be slidably fixed to the mounting rail 4.
[0019]
Here, the protrusions 6 and 6 are provided in the contact part with the mounting rail base surface 4a of the spring 5 so that the spring 5 can make point contact with the mounting rail base surface 4a.
[0020]
Further, the screw plate 3 is provided with flange portions 7a and 7b which can be slidably latched with the groove edges 4c and 4d of the mounting rail 4.
[0021]
At the bottom of the screw plate 3, chamfered portions 3a and 3b are provided.
[0022]
The spring 5 is a tape-shaped metal plate spring shown in FIG. 2B, wherein one side of the smooth surface 5b facing the mounting rail base surface 4a is bent in an arc shape, and its base end side is the chamfered portion. 3a is attached to form a slope, and the other end of the smooth surface 5b is provided with a rising portion 5a that is separated from the attachment rail base surface 4a.
[0023]
The spring 5 is formed by bending from a tape-shaped metal plate and is integrally formed.
[0024]
Furthermore, although the spring 5 is fixed to the chamfered portion 3 a by the rivet 8, the clearance 5 is provided between the screw plate 3 and the spring 5 because it is an inclined surface.
[0025]
Further, a narrow groove 9 as an anti-slip means is provided on the surface of the flange portions 7a and 7b.
[0026]
A method of mounting the mounting nut 1 thus configured to the mounting rail 4 will be described with reference to FIG.
[0027]
First, as shown in FIG. 4 (a), the clearance portion 10 (FIG. 1) of the mounting nut 1 is brought into contact with the groove edge 4d of the mounting rail 4, and the mounting nut 1 is moved in the direction indicated by arrow 14 with the corresponding contact portion as a fulcrum. The spring 5 is completely inserted into the groove 4b of the mounting rail 4.
[0028]
Next, as shown in FIG. 4B, the flange 3a side of the screw plate 3 is pushed downward while being inclined toward the groove edge 4c, the flange 7a is inserted into the groove 4b, and the flange 7a is inserted into the groove edge 4c. Position on the lower side.
[0029]
Next, as shown in FIG. 4C, the mounting nut 1 is pushed in the direction of the arrow 11 so that the flange portion 7b is positioned below the groove edge 4d. At this time, the spring 5 is compressed while the bent portion of the rising portion 5a and the smooth surface 5b abuts on the mounting rail base surface 4a and slides on the mounting rail base surface 4a in the direction indicated by arrow 15. .
[0030]
Even in such a state, the tip of the rising portion 5a contacts the chamfered portion 3a, so that the spring 5 is not compressed more than necessary and there is no fear of breakage.
[0031]
Further, by providing the chamfered portion 3b, it is easy to insert the flange portion 7b side into the groove 4b.
[0032]
After the mounting nut 1 can be pushed in until the flange portion 7b is positioned inside the groove edge 4d, the screw plate 3 is automatically indicated by the arrow 12 by the force of returning the spring 5 to the original shape when the pressing is stopped. As shown in FIG. 4D, the mounting nut 1 is sandwiched and held between the groove 4b of the mounting rail 4 and the mounting rail base surface 4a.
[0033]
Thereby, even if it is a case where the attachment rail 4 inclines, it will not move from the position once latched, and it does not slip out.
[0034]
Further, since the screw plate 3 is provided with the flange portions 7a and 7b, the mounting nut 1 can be stably latched, and the surface of the flange portions 7a and 7b is used as a non-slip means. Since the narrow groove 9 is provided, the clamping and holding between the groove 4b of the mounting nut 1 and the mounting rail base surface 4a is made stronger.
[0035]
Since the attachment nut 1 is attached to the attachment rail 4 as described above, the attachment nut 1 can be inserted and latched at an arbitrary position of the groove 4c on the attachment rail 4, not from the end of the attachment rail.
[0036]
When the mounting nut 1 is moved from the position once latched, the mounting nut 1 is pressed toward the mounting rail base surface 4a (in the direction indicated by the arrow 13 in FIG. It is moved by applying force in the direction of the position.
[0037]
Here, since the spring 5 is in point contact with the mounting rail base surface 4a by the protrusion 6, the friction between the spring 5 and the mounting rail base surface 4a is extremely small and can be moved smoothly.
[0038]
Further, since the screw plate 3 is provided with the flange portions 7a and 7b, the groove 4b serves as a guide and can be easily and reliably moved.
[0039]
[Example 2]
Another embodiment of the present invention will be described with reference to FIG.
[0040]
The mounting nut 16 has a screw 17 having a screw hole 2 and a spring 17 that can press the screw plate 3 against the mounting rail 4 at a lower portion of the screw plate 3 that can be slidably engaged with the groove 4 b of the mounting rail 4. It is configured to be slidably fixed to the mounting rail 4.
[0041]
Here, the spring 17 differs from the spring 5 in the first embodiment in the following points.
[0042]
That is, the spring 5 is formed by bending a tape-shaped metal plate spring as shown in FIG. 2B, so that the spring 5 can be brought into point contact with the mounting rail base surface 4a. The springs 17 are coil springs tapered from the mounting rail base surface 4a side to the screw plate 3 side, and the mounting rail base surface thereof. A tray 18 of a spring 17 is attached to the end portion on the 4a side.
[0043]
The tray 18 is for facilitating the sliding of the mounting nut 16 when the mounting nut 16 hooked on the mounting rail 4 is moved.
[0044]
That is, if an attempt is made to move the mounting nut 16 without mounting the tray 18, the lower end of the spring 17 is moved to the mounting rail by friction between the lower end of the spring 17 and the mounting rail base surface 4 a and bending of the spring 17. Although the attachment nut 16 cannot be moved smoothly because it is stuck on the base surface 4a, the attachment nut 16 can be moved smoothly without bending the spring 17 by attaching the receiving tray 18. be able to.
[0045]
The width of the tray 18 is a width that can be inserted into the groove 4 b of the mounting rail 4.
[0046]
In addition, the tray 18 is formed as bent end portions 18a and 18a so that both end portions thereof are not caught when the mounting nut 16 is moved.
[0047]
Further, the receiving tray 18 is provided with protrusions 19 and 19 at the contact portion with the mounting rail base surface 4a so as to be able to make point contact with the mounting rail base surface 4a. It is the same as the protrusions 6 and 6 provided in the contact portion with the mounting rail base surface 4a.
[0048]
The flanges 7a and 7b, the chamfered portions 3a and 3b, and the narrow grooves 9 provided as anti-slip means on the surfaces of the flanges 7a and 7b provided in the screw plate 3 are the same as the screw plate 3 in the first embodiment. It is.
[0049]
The mounting nut 16 constructed as described above first inserts the tray 18 into the groove 4b of the mounting rail 4, and then inserts the screw plate 3 into the groove 4b so as to be hooked on the mounting rail 4. 5 (b), the tray 18 and the screw plate 3 can be tilted by the spring 17, so that the insertion into the groove 4b can be easily performed.
[0050]
Since the attachment nut 16 is attached to the attachment rail 4 in this way, it can be attached by being inserted and latched at an arbitrary position of the groove 4c on the attachment rail 4, not from the end of the attachment rail.
[0051]
The mounting nut 16 hooked to the mounting rail 4 can be moved to a desired position in the same manner as the mounting nut 1 in the first embodiment.
[0052]
[Example 3]
Another embodiment of the present invention will be described with reference to FIG.
[0053]
The mounting nut 20 has a screw 21 having a screw hole 2 and a spring 21 that can press the screw plate 3 against the mounting rail 4 at a lower portion of the screw plate 3 that can be slidably engaged with the groove 4 b of the mounting rail 4. It is configured to be slidably fixed to the mounting rail 4.
[0054]
Here, the spring 21 differs from the spring 17 in the second embodiment in the following points.
[0055]
The spring 17 is a coil spring tapered from the mounting rail base surface 4a side toward the screw plate 3 side, and a spring tray 18 is attached to the end of the mounting rail base surface 4a side. 21 is tapered from the screw plate 3 side toward the mounting rail base surface 4a side, and at the time of compression, the small diameter side (mounting rail base surface 4a side) is sequentially accommodated to the large diameter side (screw plate 3 side). A hemispherical cap 22 is attached to the end of the small diameter side (mounting rail base surface 4a side).
[0056]
The cap 22 is for facilitating the sliding of the mounting nut 20 when the mounting nut 20 hooked on the mounting rail 4 is moved.
[0057]
In this embodiment, the cap 22 is not provided with a protrusion corresponding to the protrusion 16 in the first embodiment or the protrusion 19 in the second embodiment, but in order to be able to make point contact with the mounting rail base surface 4a. A protrusion can also be provided at the contact portion with the mounting rail base surface 4a.
[0058]
The flanges 7a and 7b, the chamfered portions 3a and 3b, and the narrow grooves 9 provided as anti-slip means on the surfaces of the flanges 7a and 7b provided in the screw plate 3 are the same as the screw plate 3 in the first embodiment. It is.
[0059]
In the mounting nut 20 configured in this way, first, the spring 21 is inserted into the groove 4b of the mounting rail 4, the cap 22 is brought into contact with the mounting rail base surface 4a, and then the screw plate 3 is inserted into the groove 4b. However, since the spring 21 is tapered from the screw plate 3 side toward the mounting rail base surface 4a side, the springs 21 are sequentially applied from the side where the cap 22 is crowned. It is easy to insert into the groove 4b, and the screw plate 3 can be inclined by the spring 21, so that the insertion into the groove 4b can be easily performed.
[0060]
Here, since the spring 21 is a coil spring in which the narrow side (mounting rail base surface 4a side) is sequentially accommodated to the wide side (screw plate 3 side) during compression, the groove 4b of the mounting nut 20 and the mounting rail base are arranged. Even when the normal length of the spring 21 is extended by increasing the number of turns of the spring 21 so as to make the clamping force between the surface 4a strong, when the spring 21 is compressed, the total length is suppressed. The mounting nut 20 can be hooked in the mounting rail 4.
[0061]
Since the attachment nut 20 is attached to the attachment rail 4 in this way, it can be attached by being inserted and latched at an arbitrary position of the groove 4c on the attachment rail 4, not from the end of the attachment rail.
[0062]
The mounting nut 20 hooked to the mounting rail 4 can be moved to a desired position in the same manner as the mounting nut 1 in the first embodiment.
[0063]
As mentioned above, although the preferable Example and usage example of this invention were described, it is not limited to the said Example and usage example, It can be set as the various form which has the same effect.
[0064]
For example, the spring is not limited to a leaf spring or a coil spring, and various other known springs can be used, and the material is not limited to metal.
[0065]
The shape of the screw plate can also be changed to various shapes depending on the shape of the mounting rail, the shape of the electric appliance to be attached, and the application.
[0066]
Moreover, it can also be set as the anti-slip | skid means which consists of a knurling or a small protrusion instead of the fine groove provided in the surface of the collar part.
[0067]
【The invention's effect】
According to the present invention, even when the mounting rail is inclined and is not tightened with bolts, the mounting nut does not move from the position where it is once hooked, and can be slipped off. There is no effect.
